SALES REGISTERING DEVICE FOR GASOLINE PUMPS Filed Feb. 5, 1959 4 Sheets-Sheet 4 BY y `M United States Patent() 3,026,032 SALES REGISTERING DEVICE FOR GASOLINE PUMPS Eugene F. Settlemire, Tucson, Ariz., assigner toGas Regv ist-er Corporation, Tucson, Ariz. Filed Feb. 5, 1959, Ser. No. 791,339 14 Claims. (Cl. 23S-94) `This invention relates to improvements in sales registering device for gasoline pumps;`

The principal objects of this invention are:

First, to provide a sales registering attachment for gasoline pumps which will permit the sales by plural attendants to be individually recorded and accumulated for each attendant as a check on the sales that have been made and the monies for which they should be individually responsible.

Second, to provide a registering mechanism interlocked with the master register of a gasoline pump which is key actuated by different keys of different operators and which requires the actuation of one of these keys' to operatively engage the register of the operator with the master register on the pump before the pump can be operated to deliver gasoline.

Third, to provide register mechanism attachable to gasoline pumps which will prevent careless or fraudulent delivery of gasoline by attendants without accounting for money received for the gasoline.

Fourth, to provide an interlock connection to the reset mechanism of the master register of a gasoline pump which will prevent the completion of the resetting operation and the releasing of the control switch of the pump until the interlock is released by actuation with a key.

Fifth, to provide individual registering mechanism of the type described which is relatively simple and inexpensive and easily attached to most of the gasoline pumps now in use.

Other objects and advantages of the invention will be apparent from a consideration of the following description and claims. The drawings, of which there are four sheets, illustrate a highly practical form of the invention as applied to a gasoline dispensing pump.

In the operation of gasoline service stations in which several dispensing pumps are operated by several attendants, it has been found difficult and impractical to eifectively check the accuracy and honesty of each attendant as the attendant might make a delivery of gasoline to a customer and fail to turn in part or all of the receipts for the delivery. While gasoline dispensing pumps currently in use are provided with a master register which shows the amount in gallons and the monetary value of each individual sale, these pumps are provided with interlock devices which require the amount of the first sale to be erased by zeroing the register prior to making a second sale. Thus unless each sale of each attendant is checked immediately upon completion, there has been noway of recording the sales which each attendant should be responsible for.

The present invention provides mechanism which necessarily requires that each attendant engage a key controlled counter or subregister assigned to him and operable only with his key prior to being able to dispense gasoline from the pump. A gasoline dispensing pump apparatus of the type commonly in use today is indicated generally at 1. Dispensing pumps of this type include a motor 2 driving the actual fluid pump 3 to deliver gasoline through the delivery hose 4. The motor 2 is under the control of an electric switch conventionally illustrated at 5 and this switch is commonly associated-with a hook 6 on the side of the pump housing so that hanging up of the nozzle 7 of the hose automatically shuts off' the motor 2 and the pump 3. In some installations a master pump delivers to a plurality of `dispensing stations and hoses and is constantly in operation in which case the switch at the dispensing station actuates a valve .in the individual hose line to permit deliveries through the hose. For the purpose of the present description the motor 2 and pump 3 in combination may be considered as a fuel supply means and the switch 5 may be considered as a switch connected to actuate and control the supply means. Practically every gasoline dispensing pump currently in use in this country includes a master register mechanism of the same design and construction. This register mechanisrn has one set of visible dials 8 which record or show the money valueof gasoline delivered. A second setof dials 9 show the volume or gallons delivered. Since these dials are for the convenience of the customer and the attendant in completing each individual sale, mechanism is provided for returning the dials to zero prior to making a second sale and a crank 10 on the'side of the pump case functions to zero the dials. Other registering devices and dials record the total money value and volume dispensing from the pump as will be described presently.

ln order to record and accumulate the volume or value of sales made by each individual of several attendants, who may operate the pump at dilferent times during the working period, the present invention provides an attendant reeorder mounted in a case on top of the pump case 1 and indicated generally by therl numeral 11.y The case encloses an upright drive shaft 12 having a plurality of beveled driving gears 13 thereon. A flexible driving connection 14 from the drive shaft 12 connects tothe master register mechanism` as will be described in greater detail. The shaft 12 is thus driven in timed relation to either the money Value dials S or the volume dials 9 whenever the pump is operated.

Pivotally'supported as at 15 on the back wall of the case 411 are a plurality of counter bodies 16 having forwardly projecting end anges 17 which support individual to accumulate totals corresponding to the rotation of the shafts as ,'will' be understood. The endsof the shafts 18` carry bevel gears 20 which are swingable verticallywith they counter bodies '16 `into engagement, withgthe drive gears 13 on the shaft 12. The dials 19 on the several counters'arevisible through openings 2li inthe case 11' to permit ready checking-of the total accumulated on each of the counters. f Y ,l

The counters 16-and the driven gears 20 carried thereby are moved selectively into engaged driving relation with the 'shaft 12 `bytneans of several key operated .locks 22 having integral ypawls 23 that are rotated by means of keys 24 between the lower position shown at 23 and the elevated position shown at 23A in FIGS. 2 and 3. In moving to theelevated position each Yof the pawls 23 engages an Varm 25 projectinglaterally from an upright slide bar 26 mounted for limited sliding motion on the back wallofthe teasing by means of the pins 27 operating in slots28. The slide bar 2 6 is urged lightly upwardly by a spring 29 but as will appear in greater detail presently, it is normally urged more strongly downwardly by spring Vtension applied to an operating'wire 3o which extends into. the pump housing 1. Pivotally supported oneaeh of thegarmsA 2.5 at 31 is a locking cam 32. The cams 32 'haveuoSesV 33,.engageable with the underside of the ilanges-ll` on the `right kends of the counter bodiesA to raise the c'ounte'rszandA resist counter clockwise rotation ofthe cams `as shown inr FIG. 2. The cams l32 als'o'have laterally'p'rojecting'arms 34 that` overlie and are engaged by the lock pawls 23 so thatthe lock cams 32'are rotated 'clockwise' to raise they counters at the same time that the liftV bar 25 is `;`raised; Springs 35 bia'sthe lock cams in a counter 4clockwise vdirection and springs 36 bias the counter bodies l16v downwardly.

Once-any lockY car'n 32 israised and its associated gear 2,0 ,engagedv by actuation of one of the locks as at 23A the lock can be returned tofdeactuated position andk the key removed so that the attendant can proceed with the business ofoper'atin'g the dispensingl pump 1. The nose 33 ,willvhold the' actuatedv cam in lposition and will hold the'eounter. body 16 in' elevated position. By mechanism to `-bef.,described; the lift 26 and the actuating wire 30 are held elevatedy until the register 8 is zeroed at which time downwardy motion of the lift bar permits disenagement of fthe nose 33 fromy the engaged counter;

rimary Register andSwitcl-z lnlterlocaks `primary register` including the dials 8 and 9 must l v'l1,r n"ed vtovzero atJ the beginning of each sale, and 4in :orden to insure that the attendant zeroes the register, interlockpmechanism iscurrently provided between the vsvt/itch andthe register zeroing crank `10. Various forms o finterlocking mechanism are provided by differentmanufacturers of gasoline pumpsbut since the interlock mechanism is -directly associated with the individual register 1,1, an example of the ,switch interlock will be describedin some detail. With reference toFIGS. 4 through 8 the frame37 which supports therdials 8 and 9 of the .primary register is illustrated as supporting the resetgshaft 38 which is actuated through the spring Vpressed jaw clutch 39 from the reset crank 10. The right end of the-,shaft 38 as appears in FIG.' 4 terminates adjacent the inside vof the casing ofthe pump 1 and carries a rotatable cam, 40, having a nose or lift 41 that rotates with the reset shaft 38. The switch 5 is mounted onthe inside of the easing lnand itsactuating element or plunger 42 is positioned to be depr essed by Ha switch actuating crank 43 rotatably mounted on thepwall of the casing by a hub 44. Exteriorly of the pump casing the Ihub 44 is provided with manually operable crank 45. This crank is desirably associated with the previously described hook 6 so that counter shafts 18. The shafts 1,18 carry dials 19 arranged hanging up the nozzle 7 automatically turnsV the crank and the actuating member 43 to open the switch 5.

FIGS. 4 and 6 illustrate the switch interlock mechanism in the pump operating, closed condition of the switch. The dotted line positions in FIG. 6 indicate the off position of the switch and the engaged position of the interlock. When the switchV actuating'member 43 is turned by actuation of the crank-45 tothe olf .position indictaed at 43A, 4the hub 44 is turned` to advance Vthe notch 46 in the hub 44 to the position'in 46A. In this position the notch 46 is openV to receive the end of anY interlock lever 47 which had previously been supported on the periphery of the hub. 4 The dotted lines at 47A indicate the" interlock engaged position of the lever. The lever 4'7 is pivotally supported on a stud 4S securedto the pump casing somewhat olfset from the shaft 33. A toggle` lever 49 swivelly mounted on the stud 48 is biased to an off-center position by the compression spring 50 compressed between the toggle lever and a fixed abutment 51. Pins 52 and 53 carried by the toggle lever alternatively'engage the interlocklever 47 on opposite sides of the stud 48 to oppositely bias the interlock lever as will be described. In the full line-position illustrated in FIG. 6, the pin 52 exerts a biasing Aforce which moves the interlock lever from the full line position to the dotted position as soon as movement of the notch 46 permits such motion. Y, v

The forward or right end of the interlock lever 47 overlies thev cam. 40 on the reset shaft 3S and in the zeroed register operating positionof the shaft and cam as illustrated, a projecting lug 54 on' the inter-lock lever isreceived in; aV notch 55 in the cam as shown in FIG. 6.

This performs the dual function of permitting motion of the interlock lever-to the full line position illustrated and also prevents operation of the reset shaft 38 and the Vassociated mechanism so long as the switch Sis closed for the delivery of fuel. When the switch actuating member 43 is turned tol off position as previously described the lug S4 moves to the dotted position illustrated at 54A releasing the cam 40 for resetope'rati'on.

The cam 40 and reset shaft 38 'can be rotatedonly in the direction indicated' in FIG. 6 by the clutch 39. Swivelly mountedon the reset shaft 38 at the outer end of the cam 40 is a keepery disc 56 having a radially projecting and axially turned pawl 57 thereon. The keeper disk is pressed into frictional driving engagement with-the endface of the cam itl by the cupped spr-ing washer 58 shown in FIG. 4 between the keeper disk and the side wall ofthe casing 1 As the cam 40 is rotatedv while resetting the register dials 8, the pa'wl 57 is carried under the end-of the interlock lever 47 and against the lugv S4 as shown at 57AV in FIG. 6. The keeper disk and its lug 57 are thus restrained against further rotation but the reset shaft 38 and cam 40 continue rotation through about 400 during which the nose `4l. on the cam engages the pin S2-and throws the toggle lever 49 olf-center with respect to the toggle spring 50 so thatV the pin 53 exerts a disengaging pressure against the left end of the interlock lever 47. Disengage? ment of the interlock lever from the notch 46'under this biasing pressure is prevented by engagement of the keeper 57 under the end of the lever 47 and by engagement of the lug S4 with the periphery of the cam 4i). v

When the resetting operation is complete the reset shaft 38 and cam 40 have traveled past the zero position of the register to an over-travel position and then returned' as will be described to the zero position illustrated in full lines. The return rotation of the cam 4l) frictio'nally rel-- turns the keeper lug 57 and realines the notch 55 with Y the lug 54 so that the interlock lever 47 moves out of the notch 46 and permits switch closing motion of the actuataoaaosa i or roller 63 projecting into the notch 69 and rotation of the cam 59 forces the roller out of the notch 60 and develops tension in the spring 64. Rotation of the crank 61 also moves the stud 65 out of the path of a cam 66 swivelly supported on the shaft 62.

Alongside of the cam disk 59 the reset shaft 38 carries a cam 67 positioned in the plane of the cam 66 and rotation of the cam 67 in the direction indicated in FIG. 8 brings the lift 68 into engagement with the nose 69 to rotate the cam 66 in a counter-clockwise direction as shown in FIGS. 7 and 8. Continued rotation of the reset shaft 3S through the previously described 4009 causes the nose 70 on the cam` 67 to engage the nose 69 and move the cam 66 to the position shown in FlG. 7. Thus in the initial rotation of the cam 67 the nose 78 passes under the stop 71 on the cam 66 but on the second rotation the nose 70 engages the stop 71 to define the limit of rotation of the reset shaft. The cam 66 is held in its locking position against the tension of the spring72 by the pawl 73 pivoted at 74 and having a keeper notch 75 engageable with the cam 66 as shown in FIG. 7. A spring '76 pulls the pawl 73 into engagement with the cam 66.

Rotation of the cam 66 moves the axially projecting pin 77 carried thereby from the full line position illustrated in FIG. 9 to the position indicated by dotted lines at 77A. The pin 77 carries one end of a link 78 which has its other end slotted and passed over a pin 79 carried by a locking lever 80 freely pivotally supported on the shaft 38. The locking lever 80 is positioned closely along side of one of the gears 81 of the register mechanism and this gear is provided with a locking stud 82 rotatable into the path of the lever 80. A spring 83 draws the pin 79 and the lever 89 into the path of the locking lug 82 when the cam 66 and the pin 77 carried thereby are advanced. The gear 81 and the locking lug 82 thereon are rotated during the reset operation, lby mechanism not illustrated, in the direction indicated by the arrow in FIG. 9 to the over-travel position of the mechanism at which point the locking lug 82 and lever 89 are operative to prevent return of the dials from the over-travel position to zero position. Return rotation of the crank 61 and the pin or roller 63 thereon under the influence of tension in the spring 64 returns the cam plate 59 and the shaft 38 from the end of the over-travel position to the zero position of the reset shaft in the direction indicated by the arrow in FIG. 7. Simultaneously the nose S4 on the crank 61 strikes the pin 85 on the previously described latch 73 to disengage the keeper 75 from the cam 66 thus permitting the cam to return to normal position. This returns the pin 77 and link 78 to the full line position shown in FIG. 9 and releases the lock lever 80 from the lug 82 permitting the gear 81 to return (opposite to the direction of the arrow in FIG. 9) from its over-travel position to zeroed position.

The foregoing interlock mechanism is as stated an example of old and existing interlocks-in the register mechanism of existing gasoline pumps. Normally the return of the mechanism from the over-travel position to the zeroed position is effected automatically as soon as the operator releases his hold on the reset crank 10. The additionsr of the present invention to this prior registering and interlocking mechanism will now be described.

Individual Recorder Interlock With Register The interlock and driving connection between the individual recorder 11 and the master register of the pump is shown most clearly in FIGS. 4 and 5. To the existing framework 37 of the register the present invention adds the vertically extending strap S6 in laterally spaced relation beside the register. An angle bracket 87 is secured to an existing stud on the framework by the nut 6 88. A cam 89 is pinned to the reset shaft 38 for rotation therewith.

The bracket 87 forms a support for the bevel gear 90 in meshed driving engagement with the existing bevel gear 91 which drives the constantly engaged accumulator 92 of the master register. The gear 91 is driven through the shaft 93 by existing connections on the register which will not be described. The new bevel gear 96 is connected to the previously described drive shaft 14 which drives the individual recorders. It will thus be seen that whenever the pump is operating the money value of the gasoline dispensed will be accumulated in the accumulator 92 and the shaft 14 will be rotated in proportion to the money value accumulated and the volume of the fuel dispensed.

The strap 86 is provided with a forwardly extending arm 94 supporting the pivot pin 95 on which an interlock lever 96 is pivotally supported. The lever 96 carries a blocking pin 97 positioned to fall into locking engagement in the notch 98 in the cam 89 when the cam and the reset shaft 38 are advanced to the full over-travel position indicated at 98A in FIG. 5 as the master register is reset. A relatively heavy spring 99 biases the lever 94 and the pin 97 to interlocked position. A yoke 160 connects the lever 96 to the previously described actuating wire 30 which operates the slide bar 26 in the individual recorder.

Cycle of Operation FIGS. 2, 4, 5, 6, 8 and 9 illustrate the mechanism in running condition in which the individual recorder 16A and its driving gear 28A are engaged with the drive shafts 12 and 14 and in which the switch 5 is closed and gasoline is being delivered as indicated by the numeral 13 on the master register dials 8 and the accumulator dials 92. When the attendant completes this particular sale and delivery and hangs the nozzle 7 on the hook 6, the switch actuating crank 45 is depressed rotating the switch actuator 43 to off position and permitting the interlock bar 47 to fall into the notch 46 under the inliuence of the toggle spring 50 shown in FIG. 6. In this condition the pump cannot be reactuated to make a second delivery or sale because of the interlock 46-47. The attendant who made the sale has had the amount thereof accumulated in his individual recorder 16A as appears in FIG. 2 andmay leave the pump to perform other duties.

A second attendant approaching the pump to make a second sale must actuate the reset crank 10 and the reset shaft 38 to disengage the switch interlock bar 47 and due to the existing interlock mechanism shown in FIGS. 7, 8 and 9 this resetting operation must be completed to the overtravel position determined lby the stops 79-71 in FIGS. 7 and 8 and the stops 80-82 in FIG. 9. The reset shaft is then pressed under returning spring tension of the spring 64 and crank 61 but automatic return from the over-travel position is prevented by engagement of the stop pin 97 in the notch 98 as shown in FIG. 5. As soon as the notch in the cam 89 registers with the pin 97, the relatively heavy spring 99 acting though the control wire 30 overcomes the relatively light spring 29 and depresses the slide bar 26 carrying with it the locking cam 24 and releasing the cam from engagement with the individual recorder 16A of the rst attendant. The first attendants recorder is thus automatically disengaged from the drive shaft 12 by operation of the spring 36 and he cannot be charged with a sale which he does not make.

The master register thus cornes to rest in the over-travel position with the switch interlock bar 47 still engaged by reason of the position of the keeper 57 at 57A in FIG. 6. In order to proceed with the second sale the second attendant must insert his key 24 in the lock of the individual recorder assigne-d to him and actuate the lock and pawl 23 to raise the associated carn 32 and the slide bar 26. The action of the key overcomes the tension of the spring 99 and raises the interlock pin 97 out of the notch at 98A thus freeing the reset shaft 38 and permitting the spring 6d and pin 63|.Y to return the cam 59 and shaft 38 from the over-travel position to zeroed positionk as previously described.` The switch interlock 47 is thus released and the second attendant can manually actuate the crank 45 to reclose the switch and start the motor 2 'for the second time. Simultaneously the cam 32 associated with the second attendants lock is engaged under the recorder 16 of the second attendant who can now remove his key and proceed with the second delivery and sale. The engagement of the interlock pin 97 with the raised periphery of the interlock cam 89 prevents the spring 99 from depressing the control wire 30 and disengaging the individual recorder until this action is purposely accomplished by resetting the master register.

The foregoing sequence'of operations achieves the object of the invention by insuring engagement of an individualfrecorder associated with an identifiable key prior to any delivery being made from the pump. The combination of interlocks also insures that the functions orv operations of fully zeroing the individual sales dials 8 and 9 will be completely carried out prior to making any delivery and sale. The operator of a gasoline service station, can thus Vbe accurately advised ofv the amount of gasoline sold by each attendant andthe attendants can be required to satisfactorily account for monies received.
